Hey folks!  While I have not seen this documented anywhere official (yet) I was just sent a list of memory caps on different SKUs of Windows 8 and Windows Server 2012.  If you have a need for speed, you are going to like the new changes!

Windows 8 Client OS

  • Windows 8: 128GB RAM
  • Windows 8 Professional, Enterprise: 512GB RAM

Windows Server 2012:

  • Server Standard, Datacenter, Server Storage Standard, MultiPoint Premium, Server HyperCore: 4TB RAM
  • Server Storage Workgroup, Server MultiPoint Standard, Server Win Foundation: 32GB RAM
  • Windows 8 Essentials Server Soultion: 64GB RAM

It has been a while since I felt my laptop just didn’t have as much RAM as it could…. but the reality is that I don’t know what I would do with more than 8GB of RAM.  Ok, I really do… Hyper-V lab environment! Smile However I do have a couple of servers with 128GB of RAM, and I don’t think I will soon come close to maxing that out for what I do! Smile

Oh, by the way: VMware announced that its limit for ESXi 5.1 (launching September 11) will be 2 TB of RAM, the same as ESXi 5.0.

    But before folks get too excited at cheap memory(16GB ecc cheaper than 6GB non-ecc [WTF]), remember to take into consideration what the MB supports per slot.
